STREET-CLEANING ATTACHMENT FOR TRACTORSi Application filed September 4, 1928. Serial No. 660,740.
This invention relates to a sidewalk or street sweeping attachment for tractors.
One object of the inventionis to provide a unitary device adapted for attachment to t a well known tractor in such manner that it may be driven directly from the take-0E gear of the tractor while permitting the ready adjustment of the rotating brush to edect the sweeping of road or sidewalk, or
w to a raised position out of contact therewith.
Another object of the invention is to connect the frame of the attachment to the front axle assembly of the tractor so that the brush it journaled in the frame of the attachment will follow the inclination of the front axle of the tractor as it tilts to conform to the inclination of the road surface.
Another feature of the invention consists in so mounting the sweepin unit that its draft strain may be'directed in line with the longitudinal plane of the tractor to eliminate so far as possible any side stress upon the latter,
With the foregoing and other objects in view which will a pear as the description proceeds the invention further resides in the general combination and arran ement of parts and details of construction ereinafter so described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.
at in the drawings accompanying this specification:
Figure 1 is a plan view of the devicewith parts broken away-showing the tractor in dot and dash lines.
Figure 2 is a side elevation of the device with the tractor in dot and dash lines, show ing the rotatable brush raised, and in dash lines the rotatable brush and itsoperating parts lowered,as when cleaning a sidewalk at or pavement.
hi re 3 is a fragmentary detail and sectiona view taken on or about line 3-3 of Figure l,
Figure dis a fragmentary detail and sec- 0 tional view taken on or about line 4-4 of Figure 1. I
The drawings indicate the well known hordson tractor including the engine housing A and also including the take-0d or all) power car A, disposed in its usual position. main supporting casing A is bolted to the engine housing of the tractor as a housing for a power take-oil shaft a, fitted with a gear A, in mesh with the power gear AK A transverse casing extension B is bolted to the casing A to receive a transmission shaft C, journaled in the extension on which is a loosely mounted beveled pinion 0 in mesh with the beveled pinion Z), keyed to the power take-01f shaft. D, is a propeller shaft connected at one end to the transmission shaft C by a universal joint D and at the other end by a universal joint I) with a shaft E, journaled in a bracket E secured to an inverted channel bar H, which is in turn bolted respectively to the forward ends of the side sills of a horizontal A-shaped frame F. The A-shaped frame F is secured to brackets A, A, extending downwardly from the underside of the tractor by longi-' tudinally aligned bolts G and G projecting through the transverse members F, F, bolted to the side sills of the A-shaped frame. In assembling the A-shaped frame with the tractor, the bolts f connecting the transverse members and the side sills of the A-shaped frame together are first slightly loosened,- the bolts G and G supported in the brackets A, A, are then connected with the transverse member F F;the bolts f, f, connecting the transverse members F, F, with the side sills of the h-shaped frame are now retightened, thereby drawing the side sills into impinging contact with the front axle of the tractor and thus making the d-shaped frame and the front axle assembly of the tractor a unit. It will new be apparent that any inclination of the axle and wheels of the tractor in traversing a road surface will be reflected in the A-shaped frame,-therefore the rotatable brush journaled in the latter,-following the inclination of the axle, will insure perfect contact between the brush and the road surface throughout the length of said brush. j
Located above the d-shaped frame and parallel with the bar H is a shaft I, journaled in'suitable bearings J carried by the bar, one end of the shaft being given an arcuate form indicated at I to which is fitted a hearing I to receive the shaft K of the rotatable brush K ,-journaled atits opposite end in a bearing L carried by a rocker arm L,
mounted upon the shaft I. A connecting link M, is secured at one end to the rocker arm L and at the other end to a manually operated lever N, pivoted at N to a segment N integral with the casing extension B. A manually operated rod N is provided for releasing the usual dog (not shown) engaging the teeth of the segment to secure the lever in its adjusted position. A spring P connected with the lever N and with a bracket secured to the frame of the machine counterbalances the weight of the brush so that the latter while bearing upon the road surface will not be subjected to excessive wear. Mounted upon the brush shaft K is a sprocket gear R connected by a sprocket chain R with a sprocket gear S carried by a short tubu'lar shaft S loosely sleeved upon the shaft I. The tubular shaft S is driven by means of the bevel gear S in mesh w1th the bevel pinion E on the shaft E in turn coupled to the propeller shaft. A
artially encircles the rotatable brush and 1s supported by brackets V secured to the inverted channel bar H. A suitable clutch member 6*, keyed to the shaft 0, and located within the transverse housing B, is actuated by a foot lever C and serves to operably connect the shaft C with the takeoff shaft a, through the tight and loose pinions b and 0 carried by the respective shafts.
As a result of the construction shown a unitary device is provided adapted to be secured to the so called Ford son tractor in such manner as to communicate its draft to the medial longitudinal axis of the tractor, and is also connected with the front axle assembly of the tractor to oscillate therewith so that the rotatable brush will follow any variations in the road surface ;it being also adjustable to carry the rotatable brush into an operative or inoperative position.
Having now indicated the several parts by reference letters, the construction and operation of the device will be readily un-. derstood.
When it is desired to sweep the walk or street the prime mover (not shown) is first started in the usual manner. The manual'l operated lever N is then shifted to the posif tion indicated in dotted lines in Figure 2,-
. the link M tilting the rocker bar L and thereby the rotatable brush into contact with the road surface as indicated by the dotted linesthe brush being actuated through the gearing connecting it with the power take-off shaft. If it is desired to stop the rotation of the brush while the motor is operating, the clutch G is actuated by means of its foot control- V ling lever C thereby disconnecting the sweeping mechanism from the power takeoff shaft. If it is desired to raise the brush out of contact with the road surface, the manually operated lever is shifted to the poguard V sition indicated in full lines in Figure 2,
:thereby' raising the brush free from contact with the road surface.
Having thus described my invention what I claim is:
